Title: Calibração de sistema de aquisição de imagem de veículo agrícola autônomo
Inventor: TYLER CALVIN NIDAY
IPC: A01B13/00
Filed: 2021-09-23
Abstract: CALIBRAÇÃO DE SISTEMA DE AQUISIÇÃO DE IMAGEM DE VEÍCULO AGRÍCOLA AUTÔNOMO. São divulgados um sistema e um método para calibrar um sistema de aquisição de imagem de uma máquina agrícola. A máquina agrícola captura imagens de objetos em um ambiente à medida que a máquina agrícola se move por um ambiente. Com base nas imagens capturadas, é gerado um modelo tridimensional (3D) representado do ambiente que representa os objetos em um espaço tridimensional. A partir do modelo 3D representado, é determinada uma localização representada de um objeto (por exemplo, edifício, poste de iluminação, árvore). A localização representada do objeto é comparada a uma localização de referência do objeto e a comparação é usada para calibrar o sistema de aquisição de imagem modificando posições, orientações ou configurações ópticas de uma ou mais câmeras no sistema de aquisição de imagem.

Title: Process of continuously producing staple fibers, particularly from mineral wool and apparatus for making the same
Inventor: KLEMENS HIRSCHMANN DR
IPC: D04H1/4209
Filed: 1992-12-17
Abstract: 2.1. The objective is to provide a process and an apparatus for the continuous production of mineral wool mats, by means of which a stable flow pattern is created in the chute, thus facilitating a clearly defined, homogeneous layer of deposited mineral wool. 2.2. According to the invention, at least one backflow region (24, 25) is generated in the chute (9) outside the fiber flow (23), which backflow region (24, 25) is sufficient for such a large-volume backflow with such a low mean velocity that appreciable upward fiber transport is avoided. In this connection, a portion (32) of the process air entrained with the fiber flow is deflected upward in the backflow, and another portion (34) of the process air is extracted. 2.3. Production of mineral wool. <IMAGE>

Filed: 1992-12-18
Abstract: ClO2 is produced efficiently by the redn. of NaClO3 in an aq. medium. The reaction is carried out at the b.pt. under reduced pressure. Pref. HClO3 and HCl react with consumption of Cl- and formation of HClO, which is reduced to Cl- by MeOH. If HClO is produced more quickly than it is consumed, it reacts with HCl to form Cl2. This hampers prodn. of ClO2 and also contaminates the prod.. Lower acidity with higher ClO3- concn. controls the rate of HClO formation. The concn. of acid (H2SO4) is below 7 N (above 5 N) and that of ClO3- is 2-6 (2.5-4) M. Partic. concns. used are mutually dependent. NaHSO4.Na2SO4 is obtd. as a by-prod.. MeOH consumption is approx. 0.2 (0.13-0.16) tons per ton of ClO2 produced; the latter is admixed with steam. The efficiency of ClO2 prodn. is at least 90% (exceeds 95%).
